In the UK, you can't send a coroner to a dead patient until a medical professional (ie crew from an ambulance) confirms life extinct. I'm unsure if the US has a similar process.
Patient Lift Assist is interesting. However, my understanding from a UK perspective is that another ambulance crew would be sent. Fire in those situations where you then need a mechanical process; I imagine fire in the US would probably be sent more often than just another ambulance crew.
Yea, its a similar process, in the State of Texas, someone at least a EMT-B can call it and at that point the sheriffs office can call it.
Back to the lift assist, yea we weren't talking about a lift as in a elevator, we were talking about it as in a obese person that the ambulance crew needs help with loading onto the stretcher and what not
